Current code has two ways to walk pte_list, the one is pte_list_walk and
the another way is rmap_get_first and rmap_get_next, they have the same logic.
This patchset tries to unify the code and also make the code more tidy.
Patch 1: KVM: MMU: introduce mmu_spte_establish, which tries to
There is little different between walking parent pte and walking ramp:
all spte in rmap must be present but this is not true on parent pte list,
in kvm_mmu_alloc_page, we always link the parent list before set the spte
to present
This patch introduce mmu_spte_establish which set the spte before
In kvm_set_pte_rmapp, if the new mapping is writable, we need to remove
all spte pointing to that page otherwisewe we only need to adjust the sptes
to let them point to the new page. This patch clarifys the logic and makes
the later patch more clean
[ Impact: no logic changed ]

If a shadow page is being zapped or a host page is going to be freed, kvm
will drop all the reverse-mappings on the shadow page or the gfn. Currently,
it drops the reverse-mapping one by one - it deletes the first reverse mapping,
then moves other reverse-mapping between the description-table.
